How are your temps and pressures?

Postby G-NIPR » Sun Nov 25, 2007 10:20 pm

Hello All,
Now that NIPR is legal again I am back in the air. The new engine has now got 13 hours on it and is purring like a well fed kitten.
I am always keen to monitor the health of my engine and would like to compare t's and p's with you all.
My oil temp has been very low and I have struggled to get it into the 30's deg. c. I have placed a plate over the bottom cowling cooling vent (as it was before the rebuild) and this has had the desired effect. I am now seeing oil temps of around 50 - 55 deg. c.

Here are my numbers from today: (readings taken at 2950 rpm / 2000 ft / OAT 4-5 deg C)

OIL temp: 52 deg C
OIL Pressure: 48 psi.
CHT: 330-350 deg F
EGT: 1250 deg F

How do they compare with yours?
They are pretty similar to before the rebuild.

Cheers for now.

Paul.

Paul,
The oil temperature gauge was deleted on production aircraft as from 1967 as being 'no longer required' (ARB approval). The gauge, as you report, never really registered a significant rise in oil temp after starting and consequently was deleted.

quote from 'amendments' 1968 owners handbook - "when oil temperature gauge has been disconnected allow two minutes warm up(more or less acording to ambient and engine temperatures)"
